67RModel

I have always wondered about this. I feel like if I were to go to Australia I would not be able to drive a manual transmission. It seems so ridiculously nuts to have to shift with my left hand since I am right handed. I don't know if I have that coordination. I guess it would be the same concept for leftys pretty much everywhere else that drive manual transmissions. I guess you just get used to it?

No I jacked the pinion up with a floor jack and just rolled the whole assembly forward by hand. I had to cage the spring chambers to release the emergency brakes but once released the whole axle assembly will roll very easily on a level concrete floor. Yes air lines can easily be shortened. If they are the new style plastic material you can simply cut them, install an new ferrule, and reinstall them into the fitting and tighten. Mine were still the original flared copper tubing. I just ended up replacing mine with all new materials and fittings since the copper was covered in hardened grease and 3 different colors of paint.

Shortening the wheelbase and driveline is a generally fairly simple project. Especially something with leaf spring rear suspension. I shortened my R model from 207" to 165" wheelbase with just basic tools last spring when I was forced to stay home for covid19 lockdown. Took about three days of work to complete but I took my time and was methodical about it. Pretty much all I needed was a 1/2" breaker bar with a 15/16" socket, 15/16" wrench, 1/2" drill, 5/8" drill bit, a tape measure, sledge hammer, and a lot of muscle. The driveshaft can be shortened by a driveline shop fairly easily and quickly once you get the rear axle bolted back in to its new location, and a final measurement. I think the shop charged me somewhere around $150 to shorten and rebalance my driveshaft. I wouldn't hesitate for a minute if all a truck needed was some wheelbase removed to be what you wanted....Attached are some of the pictures of when I shortened mine. Very doable project.

Here is another single axle diesel B model that is not rusty for sale on Ebay. https://www.ebay.com/itm/203543149764?hash=item2f641dfcc4:g:9i8AAOSwWo1hBgw8

Yes. You can buy remanufactured compressors so they can obviously be rebuilt, however I'm not certain if you can buy a parts kit to do it yourself. I'm guessing most likely but someone else on here will know for sure.

Yes the air compressors are pressure lubricated by engine oil. They also generally have a coolant line going to them too for cooling.

Here is another fairly close to me. Near Youngstown, OH. They are literally all over if you look....

4 in Scranton PA.......

I always see at least 2 or 3 for sale on Facebook Marketplace whenever I look. Granted they are not always close to me but they are definitely out there. Look on the ATHS backlot classified listings as well. Always at least one for sale on there as well. Below is a very nice one in Uniontown Ohio.....There are 2 or three very close to me on Marketplace but they are project trucks requiring considerable investment..

Yes. When you pull the pump away that machined/keyed coupler will fall out. Once you see it you will understand. It only goes back together one way. Just don't spin the engine while the pump is off.

That looks like an American Bosch pump. Removal is very strait forward. Disconnect all linkages and lines then just unbolt it from the front cover / timing gears. There should be a support underneath pump that supports the back end of it. The two bolts a real bear to access. In my opinion that is the hardest part of the job...removing and reinstalling these support bolts. Once it is unbolted it just slides out of the timing gears and lifts out. A real back breaker. It is a lot harder when it is the engine is in the truck and you are leaning over a frame rail to get to everything. It can only be installed the correct way or 180 degrees from the correct way so as long as you dont move the truck (or rotate the engine in this case) while the pump is out you will not loose the timing. There is machined metal puck that couples the pump to the timing gears much like the rubber part of a lovejoy coupler. It will fall out when you take remove the pump so be ready to catch it. The gasket to reseal the pump to the engine is still readily available from the Mack parts counter for about $12. I will look in my records to see if I can find a part number.

I don't even know where to start with this one. Running on 11R22.5 rubber with a 2.28 rear end and a T2070 you would be turning 678 rpms at 60mph and 791 rpm at 70 mph in 7th gear😂. A 4700 or 4900 series poop spreader chassis is not designed to fit a 12 or 15 liter engine under the hood so serious modifications would have to be done plus the front suspension would need beefed up....A DT 466 is only 7.6 liter by comparison. Plus I doubt either of the two larger engines' radiators would fit under the hood. I don't know you so I would never pass judgement, but in this case I will say it is just another stupid idea of yours 😅. Just change the rear end gear in the truck you buy.

This truck is on Ebay for sale. Looks like it got damaged in some type of accident.... https://www.ebay.com/itm/194216557302?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D5794447c5c4d480680f156e7047d40cf%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D194216557302%26itm%3D194216557302%26pmt%3D0%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100675.m4236&_trkparms=pageci%3Ae1afbddc-d8f5-11eb-9b10-d6abf6455abd|parentrq%3A58922e0717a0a44e6ab6a657ffec1818|iid%3A1

Why do so many LTL freight trucks from the 60s, 70s, and 80s have the front bumper cut off on the ends? You only really see it on the fleet trucks from that time. Was it a weight and/or cost saving measure? It always jumps out at me and I don't know why companies did it.

Yes. And this combination is easily worth $32,000 to somebody who wants a nice B model and realizes its going to take $30k - $40k and a year or two of their lives to build one from a $2500 pile of would be scrap metal they bought off Craigslist or Marketplace....assuming they even had the means to do a restoration. Plus you get a trailer with this one.
